Diffusion of the protein filaments F -actin confined in a thin layer between two walls is studied using the methods of single filament fluorescence imaging and particle tracking. The translational and rotational diffusion coefficients are measured for F -actin of lengths in the range of 1.5-5 microm. The length dependence of the measured diffusion coefficients is consistent with the predicted two-dimensional projection of the diffusion of a cylinder in an unbounded fluid. Fits based on the… CONTINUE READING
